HENRY E. WEBER, OF CANTON, OHIO, ASSIGNOR TO THE WEBER DENTAL MANUFAC TUBING COMPANY, OF CANTON, OHIO, A CORPORATION OF OHIO.

CUSPILDOR.

Application filed October 14, 1913.

To all whom it may concern:

Be it known that I, HENRY E. VEBER, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and use ful Improvements in Cuspidors, of which the following is a specification.

The invention relates to a cuspidor provided with the usual supply, over flow and waste pipes, and ordinarily mounted at the side of a dental or other chair; and espe cially to the cuspidors in which the supply pipe provided. with a plurality of discharge nozzles for various purposes, including the supply of water for flushing the bowl, ejecting saliva and filling a drinking cup. In cuspidors of this type the "alves for opening or closing the several discharge nozzles are by preference located close together at the side of the cuspidor, so that either one or another can be conveniently reached by a patient occupying the chair, or an operator standing adjacent thereto; and it frequently happens that the patient by mistake, or the operator by inadvertence, will open or close the wrong valve, as for instance the patient may close the valve of the bowl-flushing nozzle when intending to open the valve of the drinking-cup nozzle, or the operator may open or close the valve of the drinking-cup nozzle when desiring to open or close the valve for the saliva-ejector or the bowlflushing nozzle, In the use of such a cuspidor, it is evident that it is desirable, if not necessary for hygienic reasons, to maintain a continuous flow of water from the flushing nozzle, for constantly cleansing the bowl; and a mistaken or imldvertent closing of the flushing valve is frequently overlooked by an inattentive patient and a busy operator. Furthermore, the splashing of water from the bowl and the dripping of water from the drinking cup nozzle, fouls and corrodes the valves and adjacent parts to such an extent as to render them not only unsightly, but unsanitary, unless they are attentively cleaned by theoperator; and it has been found in practice that although an operator may be very persistent in cleaning the bowl, a like attention to the valves is usually neglected. These dii'liculties are largely overcome, and the errors of mistake or inadvertence are almost if not entirely prevented by the present invention, in which at least one of the valve hand-wheels is 10- Specification of Letters Patent.

cated to protrude a substantial distance beyond the line of the adjacent hand-wheels, and a flanged plate is employed for shielding the valves and the non-protruding handwheels.

An embodiment of the invention which has been found to be very practical and ellicient for the purpose intended, is illustrated in the accompanying drawings, forming part hereof, in which;

Figure 1 is a perspective view of a cuspidor and adjacent parts pertaining to the present invention; Fig. 2, a plan view of the same; Fig. 3, a fragmentary perspective view showing the valves and the shielding plate elevated therefrom; Fig. 4L, a section of the protruding-wheel valve and the shielding plate on line l'l, Fig. 2; and Fig. 5, an outer end view of the shielding plate.

Similar numerals refer to similar parts throughout the drawings.

The bowl 1 of the cuspidor may be 1nount ed on one branch 2, of the bracket 3, and the supply pipe at may be secured to and the over-flow pipe 5 extend from another branch 6 of the same bracket; which bracket and its branches may be tubular in form to provide waste and over-flow channels from the cuspidor bowl, and which bracket may also be swiveled on the end of the supporting arm 7, having a swinging connection, as on the pivot post 8 secured to the side of a dental chair, not shown. The supply pipe 4 may terminate in a T fitting 9 from which the branch 10 may lead through the valve 11 to the bowl-flushing nozzle 13, the branch 14 may lead through the valve 15 to the salivaejecting nozzle 16, and the branch 17 may lead through the valve 18 to the drinkingcup nozzle 19; which several valves and their respective hand-Wheels E20, 21 and 22 are preferably located in the same horizontal plane adjacent to one side and preferably just above the rim 23 of the cuspidor bowl.

It is customary to locate the drinking-cup valve between the bowl-flushing and salivaejecting valves, and for the purpose of the present invention, the hand-wheel of the former valve is located to protrude a substantial distance outside of the line of the latter hand-wheels, so that an uninformed patient or other person who desires tofill the drinking cup, will naturally and with out thought, operate the protruding valve- Wheel instead of one of the others. As a further means for inducing the same action of an uninf r e pa ie t r other pe Q and for the purpose of protecting the valves from the splashing and dripping of water, the shielding plate 24 may be horizontally located immediately above the several lves; a d, s hown: th s plate pr f ably secured on and around the upright stem 25 of the drinking-cup nozzle, and is formed to provide the dripping cup 26 for holding a drinking cup, not shown, and for receiving the drippings from the overhanging nozzle. :The inner end of the shielding plate preferably overhangs the rim 23 of the cuspidor and may be provided with the spout draining from the dripping cup 26 into the bowl lof the cuspidor; and the outer end 28 of the shielding plate preferably overhangs, to a slight extent, the non-protruding hand-wheels 20 and 21, but does not overhang the protruding hand-wheel 22; so that while the latter valveavheel may be freely manipulated without reaching under the shielding plate, the former two valvewheels can only be manipulated by reaching under tlie same. The shielding plate may also be provided with the depending flange 29 on each side and on its inner end, but this flange is omitted at the outer end of the shielding plate to permit ready access to the non-protruding valve wheels located under said end. It is evident that the depending I flange on each side ot the valves, serves to further shield. them from being operated by inadvert-ence or mistake, without in any purely illustrative and are not intended to be in any sense limiting.

I claim:

1. A cuspidor bowl, supply-pipe valves and a drinking-cup nozzle adjacent to the bowl, and a shielding plate overhanging the valves having formed thereon a drippingcup and a draining-spout leading therefrom to the bowl.

A cuspidor bowl, supply-pipe valves adjacent thereto, and a shielding plate overhanging the valves and the rim of the bowl, there being formed on the plate a drippingcup and a draining-spout leading therefrom to the bowl.

3. A cuspidor bowl, supply-pipe valves adjacent thereto, and a shielding plate overhanging the valves and the rim of the bowl.

4. A shielding plate for the supply-pipe valves of a cuspidor having formed thereon a dripping-cup and a draining-spout leading therefrom to the cuspidor.
